unlabelledView post →I was looking for a game what I like to call, 'my after work degas' and this fit the bill perfectly. The game mechanics worked fabulously and each level present a good challenge. I'd highly recommend this if you're into those old pencil type puzzles that required you to make a shape without tracing the same line twice. In short, the devs put together a really great game! Go ahead, give a try! You'll see what I mean.
positive · reviewer's own thumbsView post →one line: letters and codes is the largely similar follow-up to [url=https://steamcommunity.com/id/dohi64/recommended/1820690]one line, so my review won't be much too different either. the game still wants you to draw exactly one line on 40 levels to remove every tile, plus there are a few new mechanics on top of ones already seen. walls limit movement options, double arrows make you go in that direction until you hit a wall, other arrows place blocks on both sides of their square. the main…
positive · reviewer's own thumbsView post →This one is maybe worth buying on sale. There's very little content (beating the whole game took me barely an hour). This game is better than its predecessor "One Line" by the same devs; it feels more polished and was less frustrating to play.
positive · reviewer's own thumbsView post →He also makes such a good comment on revenge with ONE LINE (and he represents the subject of Revenge REALLY WELL THE ENTIRE GAME) "you think one day the hate will replace the pain, but in the end, it never goes away" AND ITS LIKE, FUCK
unlabelledView post →for the second half, I couldn't stop myself from cheating. :( the new mechanics in this one line game are really good and I think there were enough levels to not overstay they welcome.
positive · reviewer's own thumbsView post →I definitely enjoyed this one over the previous iteration One Line and the message at the end was unexpected and sweet. More mechanics were added to this game and it runs noticeably smoother, but I kind of hoped there was more to the code than just matching pictures....
positive · reviewer's own thumbsView post →Minimalist puzzle game, with a nice aesthetic presentation and beautiful soundtrack which make it quite relaxing. It's not very difficult, but with enough mechanics to not make it boring. And yes, you can find the solution to the puzzles if you check the hearts in the letter. But where's the fun in that?
positive · reviewer's own thumbsView post →Great value for a $1 puzzle game. Levels were a bit easier than the first one, and there were 10 less of them, but it was nice to have a theme. Took me about an hour overall. An undo-to-clicked-square button would be nice since I don't always want to fully reset the puzzle if I get one turn wrong.
positive · reviewer's own thumbsView post →It's really cheap, and pretty fun. Though at times you'll get an awfully difficult level in-between really easy ones.
positive · reviewer's own thumbsView post →Very fun and relaxing game. Strongly recommended!!
positive · reviewer's own thumbsView post →you can see the solution to the puzzles in the letter when you mouse over the hearts. Bad puzzle game and I suspect that the positive reviews are alt accounts from the devs. If you are reading this make an actually good game instead of shovelware for once and maybe you could make rent easier.
negative · reviewer's own thumbsView post →Full playthrough here: https://youtu.be/DZek5uJw0z4 I actually enjoyed the heck out of this game the creators took their minimalistic puzzle game and actually improved on it a great deal with the letter mechanic and some other in game mechanics as well for difficulty. I also guiltily really liked the fact you could see puzzle solutions while trying to figure out what puzzle piece went to what part of the letter. The music is relaxing definitely recommend checking the game out and supporting…
positive · reviewer's own thumbsView post →Same drills as the prequel with an added mechanic of filling in the blankets of a love letter, with each missing piece being one completed puzzle - but the letter also serves as a hint system: hovering over an unfinished puzzle will display one possible solution for it, so you can match the boards and use that if you're stuck in a given puzzle.
positive · reviewer's own thumbsView post →Worth the weight...
positive · reviewer's own thumbsView post →“One Line: Letters and Codes” is a slightly more polished version of the original “One Line”. It has slightly different special fields than the original, and is also a bit shorter (30 levels instead of the original’s 40 levels). If you enjoyed “One Line”, then you’ll also enjoy “One Line: Letters and Codes”. The game’s gimmick is a letter whose words need to be unlocked by solving the levels. This mechanic doesn’t really add anything to the levels themselves, but it adds a nice overall touch…
positive · reviewer's own thumbsView post →Relatively simple and short line drawing puzzle game. It is fine for what it is. Score: 5/9
positive · reviewer's own thumbsView post →Yeah this puzzle game spoils its own solutions By saying this I mean not a ‘hint’ system, as the devs suggested…You will get the answers whether you want it or not. The game will lock every 10 puzzles until the player ‘decodes’ the letter with all the solutions got so far. The pieces in the letter don’t go by the order. You are bound to get spoiled. The achievements also contain a few of them pretty patterns, but the achievements are not hidden; they are visible in the library page without even…
negative · reviewer's own thumbsView post →Another 100% Another Review: Bought This game because i Was Looking at the Dev Page After 100%ing Mewsuem Masterpieces. I Thought this game Looked Unique and a New kinda Puzzle Game to try. Did NOT Expect To Somehow get invested in a Love letter Sideplot. Im not Even Joking, every time i would beat 10 levels and go Fill it out, I would Scheme On What the Missing Words Could Be. And then After i Beat Everything? I Aint Going to Say Anything, But....Please Finish All the Puzzles if you play This…
positive · reviewer's own thumbsView post →Nice game. Quite short, but good to spend a bit of brain power.
positive · reviewer's own thumbsView post →A simple game to play, but progressively brings you a slightly more complicated challenge, though not too difficult. It also introduces new mechanics to deal with as you continue through the puzzles. Additionally, it unlocks cards that you can decipher. Very enjoyable for puzzle lovers.
positive · reviewer's own thumbsView post →Cute minimalist puzzle game. Some levels are very easy, some are quite tricky. If you get stuck, you can see the solutions on the letter page. The game is well-designed and relaxing, and I thoroughly enjoyed it.
positive · reviewer's own thumbsView post →Sequel to One Line - draw a path through the grid, following various rules. As a puzzle sequel, it's passable - I didn't think the puzzles were as tricky as the first game and there are only 40 levels instead of 50. But for 89p, I can't say I was ripped off. The extra gimmick of this one - decode a letter you've been sent - was an annoying waste of time though. After you've solved ten levels, click on the missing words in the letter and get shown a pattern, which you then match to the…
positive · reviewer's own thumbsView post →Short and relaxing puzzle game with a cosy soundtrack. The special blocks make for an interesting and not too hard challenge so it's a good game for relaxing while still using your noggin.
positive · reviewer's own thumbsView post →Quick game well worth the $1 price. Time to complete is going to vary widely based on your puzzle skills, but there aren't any hidden tricks or traps to make the puzzles harder than intended.
positive · reviewer's own thumbsView post →A captivating series of puzzle with a lovely ending. Take your time, you'll discover the feeling that awaits you.
positive · reviewer's own thumbsView post →Fun, relaxing and a game with great concept! The letter that unlock pieces with codes that you get passing the levels is a big plus!
positive · reviewer's own thumbsView post →Nice and cheap minimalist puzzle.
positive · reviewer's own thumbsView post →As good as the previous one
positive · reviewer's own thumbsView post →Easy to play, hard to master. The way I like it. Great game! Recommended!
positive · reviewer's own thumbsView post →Nice sequence. Collecting the puzzles to solve the letter is the charm of this version!
positive · reviewer's own thumbsView post →Minimalist puzzle with a lot of style and challenging. Pleasant gameplay, relaxing soundtrack. Very good to play, I liked it!
positive · reviewer's own thumbsView post →Great puzzle, beautiful letter!
positive · reviewer's own thumbsView post →Simple and relaxing. The fact of being able to move backwards allows the game to be challenging without being frustrating, simple but well-crafted concept.
